Listening to her daughter's heartfelt words, the pregnant Lady Hou went on a killing spree.

A moment later, a piercing scream came from inside the house, followed by the sound of Old Madam Yu wailing.

The commotion in the old lady's courtyard was so great that within a quarter of an hour, her sons and daughters-in-law, who had been alerted, all gathered in her room.

"Mother, what's wrong?"

The three sons and daughters-in-law were all confused. Today was their mother's 60th birthday, which should have been a happy day. What was going on?

"Boss, your sister died so tragically, waaaaah..."

The medicine in the porcelain bottle hadn't been tested by anyone yet, but just from the letter in her hand, she already believed everything Ji Yueru said today.

The eldest son of the Yu family is missing, and the younger sister has been dead for more than two years. The mother shouldn't be so heartbroken.

With trembling hands, Madam Yu handed over the letter. Before she could even finish reading it, Yu the eldest's eyes were already bloodshot.

"Lin Mufeng, how dare you!"

Yu Lao Er and Yu Lao San couldn't wait any longer, so they went to their eldest brother's side. After reading the contents, Yu Lao San slammed his fist on the table next to him, and blood splattered from his hand.

"Mother, rest assured, I will definitely kill Lin Mufeng to avenge my sister!"

"Third brother, don't be impulsive. We need to think this through carefully."

"Big brother!"

"Listen to your mother."

Yu Laoda looked at his mother, who had aged ten years in just over an hour.

"Mother, we will do whatever you say. We must avenge our little sister."

During the daytime birthday banquet, her mother's face was rosy, but now her face was ashen, and her half-gray hair was now almost completely white, which shows how much the truth had affected her.

The letter had been passed to the three daughters-in-law. Combining the contents of the letter, it was not difficult to guess the truth. The three women lowered their heads and wiped away tears, especially Zhao.

When she married the eldest son of the Yu family, her younger sister-in-law was only three years old. At that time, her mother-in-law had to take care of the business outside and her health was not very good. She was practically raised as a daughter.

Upon suddenly learning the truth, he suffered no less of a blow than the old lady.

Old Madam Yu could only weep and grieve, unable to utter a single word.

Yu Laoda knew that his mother couldn't continue like this, otherwise he really couldn't imagine how much longer she could hold on.

"Mother, you must pull yourself together! My little sister is waiting for you to avenge her. Don't you want to see the Marquis of Anshun's family suffer retribution?"

Old Madam Yu stopped crying and raised her head, her face full of sorrow, which pained her sons and daughters-in-law.

"Yes, we must avenge your sister."

Old Yu squatted down and held his mother's hands.

"Yes, we must avenge our sister; we can't let her die in vain."

Old Madam Yu's eyes lit up with renewed fighting spirit, and her sons breathed a sigh of relief.

It's good that the desire for revenge keeps them going; otherwise, they were really afraid their mother wouldn't be able to hold on.

"Your sister's child is still alive."

The group was startled again.

Where is the child?

"Lin Tianjue, the illegitimate son of the Marquis of Anshun, is the child your little sister gave birth to after risking half her life."

At this moment, the group was already heartbroken beyond measure.

How dare the Marquis of Anshun's mansion do such a thing?

The Yu family and the Marquis of Anshun's family are related by marriage, so they pay special attention to the twins, and naturally, there are people sent by the Yu family around the twins.

It's not hard to imagine what kind of life Lin Tianjue was living in the Marquis of Anshun's mansion, based on the information they brought back.

But it was precisely because of this that they were even more heartbroken. That was the child their little sister had risked half her life to give birth to, and yet it was being treated so cruelly by two illegitimate children in the mansion.

"Mother, is this true?"

"On his arm is a crescent-shaped birthmark that has been passed down through generations of men in our Yu family."

With just one sentence, the Yu family members confirmed that the child was indeed born to their younger sister.

"Boss, find a trustworthy doctor and have him examine the medicine in the porcelain bottle."

Without asking any questions, Yu Laoda assumed that the medicine in the bottle must be related to his younger sister's death. He then turned and went to the doorway to give instructions.

Everyone in the room was waiting. Half an hour later, a middle-aged man dressed in a dark robe was brought into the room, but he was not the physician that the Yu family usually used.

"Dr. Zhao, could you please take a look at what medicine is in this porcelain bottle?"

By chance, Yu Cheng saved Dr. Zhao's family and secretly helped Dr. Zhao open a clinic in the capital.

Everything was done in secret; the two families had no public dealings whatsoever.

Dr. Zhao was extremely grateful to Yu Cheng.

He took the porcelain bottle, uncorked it, took a quick sniff, and then turned his head away.

"The porcelain bottle contains a poison that came from the Western Regions. This poison is colorless and odorless, and it is undetectable when added to ordinary food. Even highly skilled doctors cannot detect it."

This poison only requires a small amount each day, but over time it can erode a person's vitality, eventually causing them to exhibit signs of exhaustion and death.

As soon as he finished speaking, Doctor Zhao was stunned. He remembered Yu Meier's death. He had taken Yu Meier's pulse before, and the pulse indicated that she had died from exhaustion and decay.

I had assumed that Yu Meier's health had been damaged during childbirth, which was why she couldn't recover and eventually died from exhaustion. But it seems that's not the case.

Despite already knowing the truth, Madam Yu was still somewhat agitated.

"Thank you for your help, Doctor Zhao."

Yu Cheng saw Doctor Zhao out of the house, and when he returned, the whole family had an angry expression on their faces.

"You may all leave. Continue with your usual routines. As for avenging your little sister, I will take care of that. I will let you know when I need you."

Yu Laosan wanted to say something more, but Yu Cheng stopped him. After leaving the house, Yu Laosan was very dissatisfied.

"Big brother, why won't you let me speak? We should all have a part in avenging our little sister."

"You know how ruthless Mother is, and in her current state, if you don't let her avenge her younger sister, she might get sick from holding it in."

Just keep an eye on Mother's movements; we'll only intervene if things get really bad.

"Third brother, listen to your eldest brother."

The three brothers had a very good relationship, and naturally, the three sisters-in-law also got along well.

"Mother, someone's here. Don't worry, he's not here to hurt you. He's probably one of Old Madam Yu's men."

A sound came from beside my ear, as if something had stuck to the edge of the bed.

Knowing that the person wouldn't harm him, he saw no need to pretend to be asleep any longer. He sat up and, by the moonlight streaming through the window, saw that what was stuck to the edge of the bed was a dart with a piece of paper pinned to it.

We'll meet at Yu's Restaurant.

The letter contained only six words, but Ji Yueru understood its meaning. It must be that Old Madam Yu wanted to meet her. It seemed she would have to find a way to leave the manor tomorrow.

[Mother, someone's here again. You should lie down quickly.]

Ji Yueru stuffed the letter under her pillow and quickly lay down. Just as she lay down, she noticed a rustling sound coming from the doorway.

"Mother, something terrible has happened! The intruders have released poisonous snakes! Get out of here right now!"
